I'm following the iclarified tutorial here http://www.iclarified.com/entry/index.php?enid=1880 and I have an unlocked 2.2(5g77) and want to update it the newest version but when I follow the instructions to restore it says restore and update which is going to update the newest software from apple. I don't know if this will brick anything but Iclarified says to restore to the downloaded software that it provides. So any help would be great on how to update my software.
